Outline of Final Research Achievements

The regrowth technique of Single walled carbon nanotubes (SWCNTs) provide a approach for growing SWCNTs with controlled chirality without catalyst.
In this study we separated SWCNTs using gel chromatography and grown by chemical vapor deposition (CVD). We optimized the CVD condition and long SWCNTs were obtained. We investigated the effect of oxydation and observed the substrate before and after CVD process to clarify whether this nanotubes were obtained by regrowth or not.
